Abstract: A method and system simulates a work process on a machine tool using a virtual machine. The virtual machine is set up to simulate the work process on the machine tool using machine data, workpiece data, and tool data as a function of numerical control (NC) control data and programmable logic control (PLC) control data. The work process is simulated on a platform that comprises a plurality of processor cores, wherein the work process is simulated in partial simulations that run in parallel on different processor cores.

Abstract: The invention relates to a device and a method for simulating a sequence for machining a workpiece on a machine tool. The invention is characterized by a holistic simulation approach. Particularly, a PLC control means 723 and a PLC sequence simulation means 725 assist in simulating the PLC movement sequences of the machine tool. This enables a realistic simulation of a machine tool in all its substantial aspects, resulting in considerable advantages especially in the field of training and during the determination of machine utilization times.

Abstract: The present invention relates to a method and apparatus for generating control data for controlling a predetermined tool on a machine tool for machining a workpiece clamped in the machine tool from a blank to a finished part. Machining geometry model data of a machining geometry of the workpiece at a machining time are compared with finished part geometry model data in order to determine a difference geometry between the machining geometry and the finished part geometry. On the basis of the determined difference geometry, a machining path is determined for the predetermined tool for removing material from the workpiece, and path data is generated such that a maximally large part of the volume of the difference geometry is removed per time unit in dependence of a maximum machining volume of the predetermined tool.

Abstract: The invention relates to a machine tool 101 comprising a plurality of operation functions and a selection device 113a-113d for selecting one or more operation functions by a user. The machine tool 101 receives data from a mobile data carrier 311 via a reception device 112, on the basis of which it may be determined which operation functions may be performed by the user. In this process, an access control device 130 grants the user access to only those selected operation functions he or she is authorized to perform.

Abstract: In a magnetic resonance tomography apparatus and a method for generating a magnetic resonance image of a subject, at least one first pulse sequence and a second pulse sequence are used for scanning k-space, with the first pulse sequence and the second pulse sequence being different from one another. A transition area, within which the first pulse sequence is converted step-by-step into the second pulse sequence, is defined between the first pulse sequence and the second pulse sequence. This prevents strip artifacts in the reconstructed image caused by phase jumps and amplitude jumps which would otherwise arise due to the transition between the different pulse sequences.

Abstract: A hair brush has a convex base formed with grooves at the floor of which are provided recesses in which the bristles are anchored. Between each row of bristles, there is formed a land by ribs upstanding from the floor of the grooves and which prevents loosened hair from accumulating at the base of the bristles.
